1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo compare Anterior Inferior Iliac Spine (AIIS) morphology between femoroacetabular impingement (FAI) and developmental dysplasia (DDH) and investigate the correlation between AIIS and hip morphology. MATERIALS AND

methods374 patients (423 hips) who underwent primary hip arthroscopic surgery were retrospectively reviewed. The inclusion criteria were patients with labral tears and either FAI or DDH. Preoperative demographics and imaging variables were compared. Patient demographics, including age, sex, and body mass index, were assessed. For imaging evaluation, the lateral center edge (LCE), sharp, vertical center anterior (VCA), alpha, and Tönnis angles and AIIS morphology according to Hetsroni's classification were assessed.

results310 patients (359 hips) were included in this study. The FAI cases involved 241 hips (148 males, 93 females), and the DDH cases involved 118 hips (34 males, 84 females). AIIS type 3 included 10 hips (4.1%) in the FAI group and 21 hips (17.8%) in the DDH group. The proportion of AIIS type 3 in the DDH group was significantly higher than that in the FAI group (chi-squared test, p < 0.001). In the FAI group, there were no significant correlations between AIIS and radiographic parameters. In the DDH group, there were significant correlations between AIIS and the LCE (R = -0.279, p = 0.002), VCA (R = -0.194, p = 0.037), and Tönnis (R = 0.241, p = 0.009) angles.

conclusionAIIS type 3 was more prevalent in DDH than in FAI patients. In DDH patients, there was a significant correlation between AIIS protrusion and the severity of dysplasia.
